PATENT I LID-.CLAMP FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 372,853, dated November8, 1887.

Application led May 26, 1887. Serial No. 239,464. (No model.)

To all whom it mayA concern:

Be it known that I, Louis K. KooNrz, a citizen of the United States,residing at Gross Lanes, in the county of Nicholas and State of WestVirginia, have invented a new and useful Improvement in Clamps forChurn-Lids, of which the following is a specication.

My invention relates to an improvement in churns,and especially tolid-clamps; and it consists in the construction and arrangement of theparts thereof, which will be more fully hereinafter described, andpointed out in the claim.

In the drawings hereto annexed, Figure lis a side view of the churn.Fig. 2 is a vertical section thereof. Fig. 3 is adetail view of thedasher. Fig. 4 is a similar view of the clamp.

Referring by letter to the drawings, A designates astone churn-tub,which ordinarily is provided around the upper edge with a flared rim,a.,an,d Bis a wooden top therefor, to which is attached the operatingmechanism of the churn.

-C designates the standard, having a horizontal arm, o, which is firmlysecured to the top B, and having a vertical bearing, c', therein.

D is the upright, havinga bracket, d, on the outer side near the center,and aligned horizontal bearings D d are 'formed in the said upright andbracket, for a purpose hereinafter explained. The upper end of theupright is reduced to form a stud, e, threaded at the upper end, and thehorizontal arm E is provided with a depending ear, E', adapted to bearon the outer side of the said upright. The said arm E also has avertical aperture, e', to receive the said stud e. A nut is screwed onthe upper end of the said stud, thus rigidly securing the horizontal armE in place, and

4o f represents a vertical bearing formed in the outer end of the saidarm.

G designatesa vertical tubular shaft adapted to operate in the verticalbearing c', and having a collar, g, to rest on the upper side of thehorizontal arm c, and the miter gear-wheel G.

H designates a shaft of the same size as the tubular shaft G, having alower reduced portion, h, to pass down through and extend a considerabledistance below the lower end of the said tubular shaft. A pintle, h', isformed on the upper end of the shaft H to operate in the bearing f, anda miter gear-wheel, H', similar to the wheel G, is secured on the saidshaft.

I designates a shaft journaled in the bearings d D' on the standard,having the large gear-wheel I on the inner end to mesh at opposite sideswith the gear-wheels G and H', and the crank-arm K on the outer end toenable the said gear-wheel to berotated. It will be readily seen thatwhen the gear-wheel I is turned the gears G and H will be rotated inopposite directions.

L designates the dasher of the churn,which is double, and consists ofthe two paddles M and N. The inner and smaller paddle, M, comprises-theradial arms M at the upper and lower ends of the same, secured rigidlyto squared portions of the reduced shaft h,which extends below thetubular shaft G, and m m are blades of the paddles reduced at the endsand set in inclined slots in the ends of the said radial arms. j

The outer and larger paddle, N, has the radial arms N at the upper andlower ends thereof, the upper arms being rigidly secured to the lowerend of the tubular shaft G, and the lower arms being provided with abearing to operate on the lower end of the shaft h. The blades a n aresecured in the said radial arms in the same manner as in the otherpaddle, and thus hold the parts of the paddle together. The said bladesm and n are so arranged in the paddles that the outer blades draw themilk or other contents of the tub inwardly toward the center, and theblades on the inner paddle throw the said contents outwardly. Thisaction causes great agitation of the said contents, especially as thesaid paddles move in opposite directions.

To secure the top of the churn firmly on the tub I provide the followingmeans: O designates'a clamp having the straight arm O', bifurcated toform the prongs O2 O2.- The outer end of the straightarm is bentdownwardly to form the depending arm P, having a transverse threadedopening, p, in the lower end to receive the thumb-screw Q, and theextremities of the prongs O'l are bent downwardly and formed into hooksR. Thestraight arm O and the prongs O2 are placed across the upper sideof the top, and the hooks R pass around the ICC edge of the said top andvbear against the side of the tub. When the thumb screw Q is screwed in,the inner end thereofwill impinge against the opposite side of the saidtub from the ends of the hooks R and hold the clamp firmly in position.As it is usual for the upper edge of the tub to be flared, as seen inthe drawings, it will be readily understood that the tendency of theclamp will he to draw down upon the lid, as the ends of the hooks andscrew will slip down on the said dared portion. It is not necessary,however, that the edge of the tub should be flared in order to make theclamp operative, as it will hold the lid rrnly in plaeeon any ordinarytub, Whether of wood, Stone, or other material.

The standard for the operating mechanism herein described is designed tobe light and strong, to enable it to be easily moved, and at the sametime to be rigid While the churn is being operated.

The dasher is designed to be easily and cheaply made, and to havestrength and great eiectiveness. The action of the parts thereof inopposite directions,with the blades arranged to violently agitate thecontents of the tub, as hereinbei'ore described, will cause the butterto be very quickly separated.

The clamp herein described is very effective and applicable to anychurn. The said clamp is also very easily applied to a churn.

Having thus described the construction, op eration, and advantages of myinvention, what I claim, and desire to secure by Letters Patent of theUnited States, is-

In combinationwith aehnrn having a flared upper edge, a lid, B, and avertical shaft, of the clamp O, adapted tohearon the upper side of thelid and comprising the main body or straight arm O', the integraldiverging arms O2 O2, passing on opposite sides of the said verticalshaft, the downwardly-turned bearinghooks R on the extremities of thearms O, adapted to engage the flared edge of one side of the churn, andthe depending arm P, formed with the extremity of the straight arm O,andhaving a thumb-screw, Q, passing through a tapped opening therein andengaging with opposite sides of the churn, substantially as described.

In testimony that I claim the foregoing as my own I have heretoaiiflxedmy signatures in presence of two Witnesses.
